If someone gets an idea they can just create a thread by theirselves.
And to your "Hide n Seek" idea: It could be funny for some people to hunt the seekers and kill them. But the game is still called Hide and Seek which means that u either hide or seek (when a seeker finds and kills you). So it´s not necessary in my opinion

Why... Why make a group thread xD But anyways the seeker is supposed to find the hiders. Not the HIDERS find the SEEKER and kill them. It could be cool though. But seekers would be at a disadvantage... being teamed up on by crafting tables and planks xD Thats a funny image xD
